How it works
Parent A has the children Monday-Thursday (4 days). Parent B has Friday-Sunday (3 days). The pattern repeats every week. Over time the split is ~57/43 in Parent A's favor.
Pros and cons
Pros
- Extremely predictable — same days every week
- Useful when one parent is the weekday caregiver and the other handles weekends
- Only 2 transitions per week
Cons
- Not 50/50 — skews toward the weekday parent
- Parent B only gets weekends, never school days
Best for
Families where one parent's weekday schedule makes them the natural weekday caregiver.
